1.3.2 Program Space
Program Space comprises the instructions to be
executed, the data required for immediate ad-
dressing mode instructions, the reserved factory
test area and the user vectors. Program Space is
addressed via the 12-bit Program Counter register
(PC register).
Program Memory Protection
The Program Memory in OTP or EPROM devices
can be protected against external readout of mem-
ory by selecting the READOUT PROTECTION op-
tion in the option byte.
In the EPROM parts, READOUT PROTECTION
option can be deactivated only by U.V. erasure
that also results into the whole EPROM context
erasure.
Note: Once the Readout Protection is activated, it
is no longer possible, even for STMicroelectronics,
to gain access to the OTP contents. Returned
parts with a protection set can therefore not be ac-
cepted.
